Question

In a typical example of static electrical discharge, a charge of 0.251~\mu\text{C}0.251 μC moves from your finger to a metal doorknob in 0.552~\mu\text{s}0.552 μs? Calculate the average current of this discharge.

Answer 1

The average current is calculated using the definition of current as charge flow in a time interval as follows :
  
where,
    is the amount of charge flow in the time interval .

So, given the values,
  
And
  
so, the average current is given by
